FOOT-OPERATED DOOR-OPENER.

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in foot operable devices foropening doors, and has for its primary object to provide a simple andeflicient device of this character which is mounted entirely upon theframe of the door.

Another object is the provision of a device of this character embodyingmeans for retracting the spring actuated bolt of the ordinary types ofdoor locks and thereby facilitate unlocking of the doOr without the useof the hands.

. Another object is the provision of means for automatically impartingan additional opening movement to the door subsequent to the release ofthe latter.

With these and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, in which:

Figure 1 represents a fragmentary side elevation of a door and doorframe, illustrating the improved door opener applied thereto,

Fig. 2 represents a fragmentary horizontal sectional view through thelower portion of the door frame, illustrating the foot operable pedal,

Fig. 3 represents a horizontal sectional view on the line 33 of Fig. 1,

Fig. 4: represents a fragmentary side elevation of the interior of thedoor frame,

Fig. 5 represents a detail sectional view through the door and doorframe, partly broken away, illustrating the opener,

Fig. 6 represents a detail sectional view on the line 6-6 of Fig. 5,

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates a door frame of the usual or any preferred Specification ofLetters Patent.

construction in which is hingedly mounted a door 6 adapted to swing toopen position 111 the direction of the arrow in Fig. 3. The door 6 isprovided with the usual type of lock including the spring actuated latch7 operable by the knob 8 and adapted to en gage in a recess 9 formed ina keeper plate 10 secured to the door frame 5.

In carrying out my invention I aperture the inner portion of the doorframe 5 in line with the recess or opening 9 in the keeper plate 10, asindicated at 12, and slidably mount a block 13 behind the opening 12upon a guide 14:. The block 13 is adapted to be moved outwardly throughthe opening 12 to engage and retract the bolt 7 of the door lock torelease the latter. The block 13 is normally retained in retractedposition by the tension of a spring 15 and is adapted to be movedoutwardly to engage the bolt 7 by a curved arm 16 carried by a shaft 17rotatably mounted in bearings 18 secured to the side members of the doorframe 5. The ends of the shaft 17 project outwardly of the door frame 5and are connected with arms 19, which, as is clearly shown in Fig. 3,are arranged upon opposite sides of the door 6, whereby the shaft 17 maybe actuated from either side.

Vertically movable pedals or platforms 20 are slidably mounted in guides21 at tached to the lower portion of the door frame 5 on oppositesidesof the door 6 and are connected with the free ends of the crank arms 19by connecting rods 22.

The upper portion of the plate 10 is formed with a horizontal slot 23,in which is slidably confined a plunger 24:, which is disposed in thepath of and adapted to be engaged and moved inwardly during the closingmovement of the door 6. A spring 25 is arranged between one end of theslot 23 and the plunger 24, and the tension thereof normally tends tomove the plunger 24 in the direction of the opening movement of the door6.

In use, the door may be opened and closed in the usual manner by meansof the knob 8, but, when desired, the door may be opened by pressingdownwardly upon either of the pedals 20, thus oscillating the shaft 17and causing the block 13 to be moved outwardly through the opening 12and engage and retract the bolt 7 WVhen the door is released, subsequentto the re- Patented Oct. 22, 1918.

traction of the bolt 7, tension of the spring 25 exerted upon theplunger 2% imparts an initial opening movement to the door.

What I claim is:

The combination with a hinged door, a door frame, and an ordinaryspring-controlled knob-operated latching bolt for said door, of anangled supporting guide positioned Within said frame, a block slidablycarried by said guide and alining With said latching bolt, said guideprovided with an elongated slot, a set screw carried by said block andriding in said slot for guiding and limiting the movement or said block,a spring connected to said block to normally hold it in retractedposition, said block provided With an opening near its inner end, ashaft rotatably carried by said frame, an arm carried by said shaft andengaging in the opening in said block to pro ject the block uponrotation of the shaft in a projecting direction, and a foot operated rodconnected to said shaft for operating the same.

In testimony whereof I aflix my signature in presence of two Witnesses.
